let R be the region between the curves defined by the functions y = x2
and y = 6−x on the interval [−3, 2]. A graph of these two functions and the x- and y-axes is shown
above. 

 

Use definite integrals and cylindrical shells to find volumes


. Set up, but do not evaluate, a definite integral for the volume of the solid obtained
by rotating R about the line x = −3.
Showing your work: Draw a typical approximating rectangle of R and the result of revolving this
approximating rectangle about the axis of rotation. Find the volume of this cylindrical shell.
